- The pinnacle handler & remote are common to saa7134 PCI boards and em28xx USB boards, so the keymap was moved to ir-common and the keyhandler is back to ir-kbd-i2c - request_module("ir-kbd-i2c") is no longer necessary at saa7134-core since saa7134.ko now depends on ir-kbd-i2c.ko to get the keyhandler Signed-off-by:Ricardo Cerqueira <v4l@cerqueira.org> Signed-off-by:

This is the patch to support TPMs on power ppc hardware. It has been reworked as requested to remove the need for messing with the io page mask by just using ioremap. Signed-off-by:

Some work is needed in the tpm device driver to discover the TPM out of the device tree rather than based on set address on Power PPC. This patch exports a couple of functions for the parsing. Signed-off-by:

put_ioctx's refcount debugging was doing an atomic_read after dropping its reference when it wasn't the last ref, leaving a tiny race for another freeing thread to sneak into. This shifts the debugging before the ops, uses BUG_ON, and reformats the defines a little. Sadly, moving to inlines increased the code size but this change decreases the code size by a whole 9 bytes :) Signed-off-by:

Sync iocbs have a life cycle that don't need a kioctx. Their retrying, if any, is done in the context of their owner who has allocated them on the stack. The sole user of a sync iocb's ctx reference was aio_complete() checking for an elevated iocb ref count that could never happen. No path which grabs an iocb ref has access to sync iocbs. If we were to implement sync iocb cancelation it would be done by the owner of the iocb using its on-stack reference. Removing this chunk from aio_complete allows us to remove the entire kioctx instance from mm_struct, reducing its size by a third. On a i386 testing box the slab size went from 768 to 504 bytes and from 5 to 8 per page. Signed-off-by:

This fixes deadlock of stop_machine() vs. synchronous IPI send. The problem is that stop_machine() disables interrupts before disabling preemption on other CPUs. So if another CPU is preempted and then calls something like flush_tlb_all() it will deadlock with CPU doing stop_machine() and which can't process IPI due to disabled IRQs. I changed stop_machine() to do the same things exactly as it does on other CPUs, i.e. it should disable preemption first on _all_ CPUs including itself and only after that disable IRQs.

This patch reverts commit c33880aa since it's not needed anymore. As pointed out by Roland McGrath the real fix is to deliver all signals before returning to user space. See http://www.ussg.iu.edu/hypermail/linux/kernel/0509.2/0683.html A fix for s390 has been merged. Signed-off-by:

The access_ok_tt() macro is bogus, in that a read access is unconditionally considered valid. I couldn't find in SCM logs the introduction of this check, but I went back to 2.4.20-1um and the definition was the same. Possibly this was done to avoid problems with missing set_fs() calls, but there can't be any I think because they would fail with SKAS mode. TT-specific code is still to check. Also, this patch joins common code together, and makes the "address range wrapping" check happen for all cases, rather than for only some. This may, possibly, be reoptimized at some time, but the current code doesn't seem clever, just confused. * Important: I've also had to change references to access_ok_{tt,skas} back to access_ok - the kernel wasn't that happy otherwise.

Paolo 'Blaisorblade' Giarrusso authored
We were using a long series of (stupid) wrappers which all call generic_console_write(). Since the wrappers only change the 4th param, which is unused by the called proc, remove them and call generic_console_write() directly. If needed at any time in the future to reintroduce this stuff, the member could be moved to a generic struct, to avoid this duplicated handling. Signed-off-by:

printk clears the host errno (I verified this in debugging and it's reasonable enough, given that it ends via a write call on some fd, especially since printk() goes on /dev/tty0 which is often the host stdout). So save errno earlier. There's no reason to change the printk calls to use -err rather than errno - the assignment can't clear errno. And in the first failure path, we used to return 0 too (and this time more clearly), which is totally wrong. 0 is a success fd, which is then registered and gives a "registering fd twice" warning. Finally, fix up some whitespace. Signed-off-by:

A few fixups - show the new submenu only for x86 subarchitecture (it does not make sense to show it for x86_64 users) and remove X86_CMPXCHG, which is now a duplicate of Kconfig.i386, even though Kconfig doesn't complain (we also miss the dependency on !M386 CPU). Signed-off-by:

The below warning was added in place of pte_mkyoung(); if (is_write) pte_mkdirty(); In fact, if the PTE is not marked young/dirty, our dirty/accessed bit emulation would cause the TLB permission not to be changed, and so we'd loop, and given we don't support preemption yet, we'd busy-hang here. However, I've seen this warning trigger without crashes during a loop of concurrent kernel builds, at random times (i.e. like a race condition), and I realized that two concurrent faults on the same page, one on read and one on write, can trigger it. The read fault gets serviced and the PTE gets marked writable but clean (it's possible on a shared-writable mapping), while the generic code sees the PTE was already installed and returns without action. In this case, we'll see another fault and service it normally. Signed-off-by:

In Uml, many definitions are borrowed from underlying subarch headers (with #include <asm/arch/stuff.h>). And it has become annoying to keep switching tag files all time, so by default index the underlying subarch headers too. Btw, it adds negligible space to the tags file (less than 1M surely, IIRC it was around 500k over 40M). Finally, preserve the ALLSOURCE_ARCHS command line option (I hope) - if it is set, it is used for headers too as before. But check my construct please, I didn't test this. Signed-off-by:

Remove task_work structure, use the standard thread flags functions and use shifts in entry.S to test the thread flags. Add a few local labels to entry.S to allow gas to generate short jumps. Finally it changes a number of inline functions in thread_info.h to macros to delay the current_thread_info() usage, which requires on m68k a structure (task_struct) not yet defined at this point.

a) in smp_lock.h #include of sched.h and spinlock.h moved under #ifdef CONFIG_LOCK_KERNEL. b) interrupt.h now explicitly pulls sched.h (not via smp_lock.h from hardirq.h as it used to) c) in three more places we need changes to compensate for (a) - one place in arch/sparc needs string.h now, hardirq.h needs forward declaration of task_struct and preempt.h needs direct include of thread_info.h. d) thread_info-related helpers in sched.h and thread_info.h put under ifndef __HAVE_THREAD_FUNCTIONS. Obviously safe. Signed-off-by:
